Description
Growth differentiation factor 2 (GDF2) is a protein also known as bone morphogenetic protein (BMP)-9 that belongs to the transforming growth factor beta superfamily. It has a role in inducing and maintaining the ability of embryonic basal forebrain cholinergic neurons (BFCN) to respond to a neurotransmitter called acetylcholine; BFCN are important for the processes of learning, memory and attention. GDF2 is also important for the maturation of BFCN. Another role of GDF2 has been recently suggested. GDF2 is a potent inducer of hepcidin (a cationic peptide that has a antimicrobial properties) in liver cells (hepatocytes) and can regulate iron metabolism
